Properties of Spectrally Bounded Compact Elementary Operators
(DOI: 10.47443/cm.2021.0012, 2021-03-31)
Spectrally bounded compact elementary operators on dense irreducible subalgebras of C ∗ -algebras are characterized. Also, it is shown that left multiplications, right multiplications, generalized derivations and basic ...
Sensitivity Analyses of Population Projection Matrix of Cestrum Aurantiacum
(Kenya Forestry Research Institute/Jaramogi Oginga Odinga University of science and Technology., 2020)
The Lefkovitch stage specific matrix population models are divided into discrete stage classes defined by a growth variable such as size, height and diameter at breast height for trees. In matrix model, the deterministic ...
Extensions of Lefkovitch Matrix for Modeling Invasive Cestrum Aurantiacum Population Dynamics
(KEFRI/, Jaramogi Oginga Odinga University of science and Technology., 2020)
Modeling of invasive species using stage based matrix methods can be exploited to understand population dynamics of plants using stage based Leftkovitch matrix models. This study reviewed and extended the stage based matrix ...
Sweet Potato Leaf Spot Diseases and Farmer’s Indigenous Knowledge in Parts of Western Kenya
(International Journal of Research Studies in Agricultural Sciences (IJRSAS), 2021-11)
Sweet potato (Ipomoea batatas L.) is a starchy, tuberous root with worldwide consumption.
Production of sweet potatoes in Kenya is low due to disease constraints, such as fungal sweet potato leaf spot (SPLS), which is not ...
Evaluation of CO2 in Saline Aquifers under Deep Ground Water Systems in Urumqi River Basin of Xinjiang, China
(Ecological Engineering & Environmental Technology, 2021-09-17)
The future emissions of carbon dioxide (CO2) are likely to increase beyond the current levels due to rapid industrialization in China. Several methods have been proposed as possible mitigation strategies to reduce the ...
Inventory, reward value and diversity of Apis mellifera nectariferous and polleniferous forage in Eastern Mau forest, Kenya
(International Journal of Scientific and Research Publications, 2020-02)
The study was conducted in Eastern Mau is one of the East Mau forest is an important watershed within the Mau Forest Complex, feeding major rivers and streams that make up the hydrological systems of Lake Victoria and ...
Optimal Allocation in Small Area Mean Estimation Using Stratified Sampling in the Presence of Non-Response
(International Journal of Statistical Distributions and Applications, 3/12/2021)
Sample survey provides reliable current statistics for large areas or sub-population (domains) with large sample sizes. There is a growing demand for reliable small area statistics, however, the sample sizes are too small ...
Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal of Multidisciplinary Sciences and Engineering, 2020)
In this paper, a nonlinear fourth order evolution equation is investigated by the Lie symmetry analysis approach. All the geometric vector fields and the Lie groups of the evolution equation are obtained. Finally, the ...
Volatility Estimation Using European-Logistic Brownian Motion with Jump Diffusion Process
(International Journal of Mathematics And its Applications, 2020)
Volatility is the measure of how we are uncertain about the future of stock or asset prices. Black-Scholes model formed the foundation of stock or asset pricing. However, some of its assumptions like constant volatility ...
Lie Symmetry Analysis of Modified Diffusive Predator-prey Competition System of Equations
(International Journal Of Multidisciplinary Sciences And Engineering, 2020-03)
The predator-prey equations were developed and used by Lotka and Volterra to analyze the dynamics of biological systems in which two species interact, one as a predator and the other as prey [3]. Several attempts have been ...
